DEPRECATED. This shader is unsupported, but it may still get installed with Softimage to provide compatibility with older scenes that use it. It is recommended that you replace unsupported shaders in your scenes with equivalent shaders from the current Softimage shader library.
Shader Type: Environment (Legacy)
Takes a single image file and maps it to the environment using a spherical mapping. It wraps the image around the Y axis of an imaginary sphere. This is done using longitude and latitude transformations. Just as the longitude lines on a globe move closer at the poles, the image is pinched at the top and bottom of the sphere. The seam where the left and right parts of the image meet is in the negative Z direction.
